<b>Description: DB_MPOOLFILE-&gt;set_ftype</b>
<p>The DB_MPOOLFILE-&gt;set_ftype method specifies a file type for the purposes of
input or output processing of the file's pages as they are read from or
written to, the backing filesystem store.</p>
<p>The DB_MPOOLFILE-&gt;set_ftype method configures a file in the memory pool, not only
operations performed using the specified <a href="../api_c/mempfile_class.html">DB_MPOOLFILE</a> handle.</p>
<p>The DB_MPOOLFILE-&gt;set_ftype method may not be called after the <a href="../api_c/memp_fopen.html">DB_MPOOLFILE-&gt;open</a> method is
called.
If the file is already open in the memory pool when
<a href="../api_c/memp_fopen.html">DB_MPOOLFILE-&gt;open</a> is called, the information specified to DB_MPOOLFILE-&gt;set_ftype
will replace the existing information.</p>
<p>The DB_MPOOLFILE-&gt;set_ftype method
returns a non-zero error value on failure
and 0 on success.
</p>
<b>Parameters</b> <br>
 <b>ftype</b><ul compact><li>The <b>ftype</b> parameter sets the file's type for the purposes of input
and output processing.  The <b>ftype</b> must be the same as a
<b>ftype</b> parameter previously specified to the <a href="../api_c/memp_register.html">DB_ENV-&gt;memp_register</a> method.
(See the <a href="../api_c/memp_register.html">DB_ENV-&gt;memp_register</a> documentation for more information.)</ul>

<b>Description: DB_MPOOLFILE-&gt;get_ftype</b>
<p>The DB_MPOOLFILE-&gt;get_ftype method returns the file type.</p>
<p>The DB_MPOOLFILE-&gt;get_ftype method may be called at any time during the life of the
application.</p>
<p>The DB_MPOOLFILE-&gt;get_ftype method
returns a non-zero error value on failure
and 0 on success.
</p>
<b>Parameters</b> <br>
 <b>ftypep</b><ul compact><li>The DB_MPOOLFILE-&gt;get_ftype method returns  the
file type in <b>ftypep</b>.</ul>
